Mine had dropped as much as 8 inches in front of the garage door, I had it done about 3 years ago and it hasn't moved a bit since then.
But I had to fix the problem behind the problem too - chipmunks! They had tunneled under the drive and the voids they made allowed water to erode the dirt from under the slab.
Once I got rid of them, and mudjacked the driveway back up, end of problem.
nice...we need to have the porch at the side of our house done as it is sloping towards the house.
Mind if I ask what it cost?
